说明

TUSB422 是一款 USB PD PHY,可在 USB
Type-C 端口中实现 USB Type-C 生态系统所需的配置通道 (CC) 逻辑。该器件集成 USB 双相标记编码 (BMC) 供电 (PD) 协议的物理层,允许使用功率高达 100W 的电源并支持备用模式接口。具备 USB Type-C 端口管理器 (TCPM) 的外部处理器通过 I2C 接口与 TUSB422 进行通信。

在 TCPM 的控制下,TUSB322 使用 CC 引脚确定端口连接状态、电缆方向并进行角色检测和 USB Type-C 电流模式控制。TUSB422 可根据应用配置为 DFP、UFP 或 DRP。TUSB422 应用 VBUS 检测和放电功能,从而实现兼容性 USB Type-C 端口。

TUSB422 集成 2.5W 开关,可为有源电缆提供 VCONN 电源。该器件还提供 VCONN 放电功能。TUSB422 还支持 USB Type-C 可选 功能, 例如音频和调试附件。

该器件能够在宽电源范围内工作,功耗较低。TUSB422 可在工业级温度范围内运行。
